A simple point-to-point radio system can be created with the kit components and a Windows-based PC. One end of the communication system is created with a standalone P160 Bluetooth module connected via USB or RS232 to a Windows PC. This PC runs the evaluation version of the BTExplorer application, which executes the Bluetooth stack within the Windows environment. The other radio system uses the Spartan-IIE board and second P160 Bluetooth module. The Spartan-IIE platform implements a MicroBlaze design, combining the evaluation Bluetooth binary stack and serial port profile with your application code. An optional second PC connects to the Spartan-IIE board for user feedback and control. Figure 3 shows the functionality of the P160 Bluetooth module based on Broadcom’s BCM2035 – a monolithic, single-chip, baseband processor with an integrated 2.4 GHz transceiver for Bluetooth v1.1 and 1.2 applications. It minimizes the footprint and system cost of implementing a Bluetooth link by integrating all critical components into the device. The BCM2035 is an ideal solution for any voice or data application that requires the Bluetooth standard Host Controller Interface (HCI) via either UART or USB, and PCM (pulse code modulation) audio interfaces. The integrated microprocessor unit stores the lower level protocol stack in ROM plus patch RAM to provide the maximum flexibility while eliminating the need for external flash memory for the lower stack. The BCM2035 radio transceiver provides enhanced radio performance to meet the most stringent industrial temperature applications or the tightest integration into portable devices. It provides the highest available radio performance of any singlechip device with -90 dBm sensitivity and +7 dBm programmable output power. Development System Capabilities The Spartan-IIE board from Memec Design provides all the necessary features for implementing a simple MicroBlaze design. The board includes the P160 expansion module slot for connection to the Audio Connector Power Connector USB Connector RS-232 Connector 3.3V Reg Power Switch UART Interface IOPB DOPB MicroBlaze Processor DL/MB IL/MB 1.8V Reg P160 Bluetooth module, SDRAM, serial port, and miscellaneous support circuits. Figure 4 shows an example MicroBlaze system that incorporates the Bluetooth interface. Because the Bluetooth module looks like a standard serial port to the MicroBlaze system, the only hardware modification required to the system architecture is the addition of a UART block. The Memec Design Embedded Bluetooth Development Kit includes a fully P160 Connector P160 Bluetooth Card functional evaluation version of Stonestreet One’s Bluetopia protocol stack. An implementation of the upper Bluetooth protocol stack, the Bluetopia software eases application development by providing a robust yet easy-to-use development tool that implements the Bluetooth protocols above the HCI. The Bluetopia application programming interface (API) provides access to the upper-layer protocols, including Logical 66 Xcell Journal Fall 2003 Op Amp Audio Codec Jumper Jumper RS-232 TX/RX Sleep Mode Interface BCM2035 Single Chip Bluetooth GPIO Header P160 Connector Reset Switch EEPROM Xtal 15.36 MHz Figure 3 – P160 Bluetooth Module functional diagram OPB Memory Controller Spartan-IIE FPGA UART UART JTAG UART GPIO Output Port Memory Controller Memory Controller Block RAM (16K Bytes) Spartan-IIE Development Board Serial Port Debug Port LCD SDRAM Figure 4 – Typical MicroBlaze-based system T/R Switch Memory Serial Port EEPROM Bluetooth Transceiver (BCM2035) SRAM Flash USB RF Connector Audio CODEC P160 Bluetooth Module
User Application and Bluetooth Protocol Stack Executing on MicroBlaze Processor Broadcom BCM2035 Bluetooth Transceiver OBEX RFCOMM Link and Adaptation Protocol (L2CAP), Service Discovery Protocol (SDP), RFCOMM protocol, and OBEX protocol. Bluetopia software also provides APIs for all mandatory and most optional profiles. In addition, Stonestreet One provides lower level HCI transport drivers to interface to various Bluetooth devices such as the BCM2035. These lower level HCI drivers have been written to support the addition of new HCI transport drivers with little or no change to existing applications. The evaluation version of the Bluetopia protocol stack provides support for the following Bluetooth protocols: HCI, L2CAP, SDP, and RFCOMM. The Bluetopia stack also provides support for generic access profile (GAP) and serial port profile (SPP) Bluetooth profiles. Figure 5 illustrates an example Bluetooth protocol stack. In addition to the above listed protocols and profiles, Stonestreet One will make available an extensive suite of existing and future Bluetooth protocols/profiles as required. Full development or production versions are available through license from Stonestreet One along with additional profiles if required. BTExplorer is a user-friendly Windows Applications Profiles SDP L2CAP Link Manager Link Controller Baseband Radio TCS Host Controller Interface Figure 5 – Bluetooth protocol stack application that is used to connect and manage Bluetooth devices. BTExplorer discovers Bluetooth devices in the vicinity and presents them in an easy-to-understand format similar to Windows Explorer. As used in the development kit, BTExplorer facilitates a simple peer-topeer system. When connected to the standalone P160 Bluetooth Module, BTExplorer provides the upper stack capability to the module, thus creating a complete Bluetooth node. Conclusion The Memec Design Embedded Bluetooth Development Kit allows designers to enhance any new or existing MicroBlazebased designs with the addition of a Bluetooth interface. By providing a MicroBlaze-specific port of the Bluetooth stack along with the necessary prototyping hardware, the kit eases the development process, shrinks the design cycle, and speeds your time to market. The Embedded Bluetooth Kit is available for $1,495 from Insight Memec at www.memec.com/insight-memec/. Plans are under way to develop a similar development kit utilizing the new Xilinx Spartan-3 FPGA.
